At that point, all you have is a chassis built to handle with more power than it was designed to hold, going in a straight line. Why ruin an S2000 to do it? Pick some common RWD car and mod that instead. A Mustang with solid rear axle would seem the obvious choice (or a Camaro).

Honestly the motor was one of the big draws for me and has kept my S2000 in the garage for nearly 14 years. I like the ingenuity of going electric, but definitely prefer the F20C. And I have never been a fan of purpose built dragster S2000s either, negates the other engineering genius of the S2000's design, the suspension and chassis.
